Engine fuel consumption measurement device and measurement method

Abstract

The invention discloses a device and method for measuring fuel oil consumption of an engine and belongs to the field of engine fuel oil detection equipment. The device is provided with an auxiliary oil tank (11). One end of an engine oil inlet pipe (5) and one end of an engine oil outlet pipe (6) are connected with the engine, and the other end of the engine oil inlet pipe (5) and the other end of the engine oil outlet pipe (6) are inserted into the auxiliary oil tank (11). A high liquid level sensor (8) is arranged on the upper portion of the auxiliary oil tank (11), a low liquid level sensor (9) is arranged on the lower portion of the auxiliary oil tank (11), and the auxiliary oil tank (11) is connected with a large engine oil tank (13) through an oil pipe (2). The measurement method includes the steps that after a system is powered on, whether the engine operates or not is judged; whether power failure exists or not is judged; whether a high oil level signal exists or not is judged; whether a low oil level signal exists or not is judged, and then corresponding control is carried out; the auxiliary oil tank is adopted for detecting and controlling oil inlet amount in real time. By means of the device and method, the oil consumption of the engine can be accurately measured, cost is low, and the problems of oil return pulsation and bubbles of the engine are effectively solved. The device and method have the advantages of being good in measurement real-time performance and the like.

Description

technical field [0001] The invention discloses a measuring device and a measuring method for fuel consumption of an engine, which belong to the field of fuel oil testing equipment for engines. Especially suitable for motors where the fuel is liquid. Background technique [0002] In the context of rising fuel prices and the country's advocacy of a conservation-oriented society, providing engine fuel consumption is helpful to understand engine fuel consumption, and can also provide a measurement tool for fuel saving. The existing engine fuel consumption detection device mainly calculates the diesel engine fuel consumption by measuring the remaining fuel in the fuel tank, which has low measurement accuracy and poor real-time performance. The existing engine fuel consumption detection device uses two flow sensors, which are respectively installed on the oil inlet and outlet oil pipes of the diesel engine, and subtracts the measured oil output from the measured oil inlet to obta...

AI Technical Summary

Problems solved by technology

The disadvantages are that using two flow sensors will greatly increase the cost, and the oil return of the engine is pulsating and may contain air bubbles, which cannot be accurately measured

The oil return flow of the engine is small, which cannot be measured by general flow sensors, especially for small displacement engines

It can be seen that the existing engine fuel consumption measurement device has problems such as low accuracy and high cost.
